Design Around Bundle Patent Portfolio Based on Technological Evolution

Product innovation can be achieved by analyzing leading products patents in the market.Different methods have been proposed for design around patent,commonly using the elimination or replacement of a single patent element However,the existing research fails to restore the position and function of the design around object in the original patent portfolio of enterprises,which often leads to the phenomenon of evading one patent and violating another.This paper proposes a method for design around patent through using the fusion of technologies of the evolution theory and bundle-type patent portfolio analysis in the initial stage of product development.The object system is analyzed to select technical opportunities through the evolutionary path of technologies and functional trimming methods to achieve circumvent barriers of bundle-type patents.The bundle patent portfolio is analyzed for the product evolution with a radar map.The technological evolution path is combined with the TRIZ innovation method to identify and solve the design problem.Patentability of the new design is evaluated using the patent system rules for innovative scheme difference from the original patent portfolio.The method is verified in a case study for the design of a glass-wiping robot.The design solution has been patented.

Impact Performance Research of Re-Entrant Octagonal Negative Poisson’s Ratio Honeycomb with Gradient Design

Based on the traditional re-entrant honeycomb,a novel re-entrant octagon honeycomb(ROH)is proposed.The deformation mode of the honeycomb under quasi-static compression is analyzed by numerical simulation,and the results are in good agreement with the experimental ones.The deformation modes,mechanical properties,and energy absorption characteristics of ROH along the impact and perpendicular directions gradient design are investigated under different velocities.The results indicated that the deformation mode of ROH is affected by gradient design along the direction of impact and impact speed.In addition,gradient design along the direction of impact can increase the initial peak stress of ROH and accelerate its densification phase.Gradient design perpendicular to the impact direction can enhance the energy absorption performance of ROH,especially for ROH,with wall thickness increasing from the inside outwards.Compared to ROH with uniform wall thickness at the same relative density,ROH with a gradient design can increase the plateau stress by over half.With the elevation of impact velocity,the plateau stress and specific energy absorption exhibit an upward trend,aligning with the dynamic performance pattern observed in conventional honeycombs.The results can be used as a reference for the design and application of honeycomb and provide a new idea for developing more efficient and reliable energy-absorbing materials.

Technological progress and prospects of reservoir stimulation

Through reviewing the development history of reservoir hydraulic fracturing technology, this paper demonstrated the latest research progress at home and abroad and summarized six technical gaps between China and the world, that is fracture propagation mechanism, fracturing software development, fracturing vehicle equipment, downhole tools temperature and pressure resistance, proppant replacement and big data information database. The technical difficulties include lack of geological-engineering deep integration, unclear factors on horizontal well multi-fracture propagation, difficulty in reducing construction costs, environment protection pressure, lack of new experimental and field test equipment, immature techniques for fracturing fluid, and low efficacy of factorized fracturing equipment. We proposed six suggestions on China’s future reservoir hydraulic fracturing technology:(1) strengthen the mechanism study of unconventional reservoir hydraulic fracturing;(2) accelerate the development of geological-engineering integration software;(3) promote the upgrading of EOR fracturing techniques;(4) carry out low-cost multi-functional fracturing fluid formula experiment;(5) complete high-efficiency fracturing equipment;(6) build big database, informational and remote decision-making system of hydraulic fracturing.

The dark side of technological advances in analysis of microbial ecosystems

Recent technological advances mean that samples from animal experiments may be analysed more cheaply,more easily and with a much greater return of data than previously.Research groups are frequently faced with a choice of continuing to use established technology in which they may have made a significant investment of time and resources,and have significant amounts of reference data,or switching to new technology where reference data may be limited.Apart from cost,the choice needs to be based on a comparison between the increase in data available from future experiments by switching and the value of comparison with reference data from historical experiments analysed with earlier technology.One approach to this problem is to ensure that sufficient quantity and variety of samples are taken from each experiment and appropriately stored to allow re-establishment of a sufficiently large reference set and to avoid the need to repeat animal experiments.The establishment of ‘biobanks' of experimental material will require funding for infrastructure,consistent storage of metadata and,importantly,horizon-scanning to ensure that samples are taken appropriately for techniques which will become accessible in future.Such biobanks are a recognised resource in human medicine,where the value of samples increases as more analysis is carried out and added to the metadata.

Process Characterization of the Transesterification of Rapeseed Oil to Biodiesel Using Design of Experiments and Infrared Spectroscopy

For optimization of production processes and product quality,often knowledge of the factors influencing the process outcome is compulsory.Thus,process analytical technology(PAT)that allows deeper insight into the process and results in a mathematical description of the process behavior as a simple function based on the most important process factors can help to achieve higher production efficiency and quality.The present study aims at characterizing a well-known industrial process,the transesterification reaction of rapeseed oil with methanol to produce fatty acid methyl esters(FAME)for usage as biodiesel in a continuous micro reactor set-up.To this end,a design of experiment approach is applied,where the effects of two process factors,the molar ratio and the total flow rate of the reactants,are investigated.The optimized process target response is the FAME mass fraction in the purified nonpolar phase of the product as a measure of reaction yield.The quantification is performed using attenuated total reflection infrared spectroscopy in combination with partial least squares regression.The data retrieved during the conduction of the DoE experimental plan were used for statistical analysis.A non-linear model indicating a synergistic interaction between the studied factors describes the reactor behavior with a high coefficient of determination(R^(2))of 0.9608.Thus,we applied a PAT approach to generate further insight into this established industrial process.
